Nowadays, the competitiveness of various industries is becoming greater and greater. The same is true for bubble film manufacturers . In addition, the state encourages the recycling of resources. Many bubble film manufacturers have begun to use new materials and recycled old materials for production. Increased profits of manufacturers to a certain extent. However, the whiteness and transparency of the bubble film produced from recycled plastic are often unsatisfactory. In order to solve the appearance problem of the bubble film of recycled plastic, you can choose to add a fluorescent whitening agent for bubble film to increase the whiteness of the bubble film.
